Hodoodo CAT#: H407449
CAS#: 1702259-66-2
Description: H3B-6527 is a potent and orally active FGFR4 inhibitor with potential antineoplastic activity. Upon administration, H3B-6527 specifically binds to and blocks FGFR4. This prevents the activation of FGFR4, inhibits FGFR4-mediated signaling and leads to an inhibition of cell proliferation in FGFR4-overexpressing tumor cells.

More Info: FGFR4, a receptor tyrosine kinase overexpressed by certain tumor cell types, is involved in tumor cell proliferation, differentiation, angiogenesis, and survival; FGFR4 expression is associated with poor prognosis.
Biological target: | H3B-6527 is a covalent FGFR4 inhibitor with an IC50 value of <1.2 nM and at least 250-fold selectivity over FGFR1-3 (IC50 values of 320, 1,290 and 1,060 nM respectively). |
In vitro activity: | H3B-6527 treatment resulted in a GI50 value (concentration of inhibitor that led to a 50% reduction in viability) of 25 nmol/L (Fig. 2E). Furthermore, H3B-6527 treatment of Hep3B cells led to robust activation of caspase-3/7, an apoptotic marker, in a concentration-dependent manner, indicating FGFR4 inhibition by H3B-6527 leads to cell death in HCC cell lines (Fig. 2F). In summary, these data show that H3B-6527 inhibits proliferation and leads to apoptosis in a HCC cell line by inhibiting FGFR4 signaling.

In vivo activity: | Furthermore, ESCC tumors in nude mice responded to H3B-6527 treatment with an apparent slowing of growth. At 20 days of H3B-6527 treatment, the speed of ESCC tumor growth was reduced and the tumor volume was significantly smaller. On the contrary, the control group treated with physiological saline exhibited no significant inhibitory effects. These findings indicate that FGFR4 blocking is effective in inhibiting the growth and survival of ESCC cancer cells in xenograft models. A dose-response effect of tumor regression may be achieved with higher doses of H3B-6527 administered for longer periods (20 days). The effectiveness of H3B-6527 in ESCC tumor xenografts may be linked to the blocking of FGFR4 in human ESCC cancers. Therefore, FGFR4 may become a potential target and H3B‐6527 may be useful for ESCC cancer patients with FGFR4 overexpression.
